IMPROVEMENT IN FLOATS FOR SUCTION-PIPES OF PUMPS.

Specification forming part of Letters Patent No. 159,599, dated February9, 1875; application filed October 9, 1874.

To all whom it may concern Be it known that we, CHARLES MEITZLER and G.HERMAN HAAss, both of the city of Rochester, in the county of Monroe andState of New York, have invented a certain new and useful Improvement inPumps; and we do hereby declare that the following is a full, clear, andexact description of the construction and operation of the same,reference being had to the accompanying drawings, in which Figure 1 is asectional elevation, showing our improvement applied to a cistern. Fig.2 is a perspective view of the float removed from place andturned uponone side.

This invention relates to improvements upon that class of apparatus inwhich a float is used in a cistern to support one end of a pipe near thesurface of the water, whereby, when the pump is operated, only the puresurface water is supplied. The invention has for its object to supportthe body of pipe above the water as the float falls; and it consists ofthe combination of an elevated platform with a floating block andnozzle, constructed and operating as hereinafter described.

In the drawings, A represenfs the float, through which passes the nozzleB, to the upper end of which is attached the flexible tube G, extendingto the pump, and connecting therewith in any desired manner, so thatsuction can be applied, by means of the pump, through the flexible tube,thereby raising the liquid. The float consists of two partsan elevatedplatform, a, and a floating block, I), attached beneath it. The blockforms the float proper, and rests submerged in the liquid, while theplatform, which is of larger size, remains above the surface of theliquid and serves as a rest or support for the bends of the flexibletube, or other bodies which may rest thereon, either side of the center,without tilting or upsetting the device. Its object is specially toaccomplish this result, and it is important in large floats, forinstance, for fire-engines, where the weight of the hose lying thereonwould be considerable, and, if placed on one side, would upset the floator submerge it, so as to discharge the hose. In the latter case, itmight also serve as a support for an attendant. Another object is toelevate or raise the platform some. distance from the water, so as notto wet the The nozzle is simply insertarticles thereon.

ed through the float, and may be held by shoulders 0 c on oppositesides. The upper end, 01, which projects through the float, is bent at asuitable angle for the attachment of the flexible tube, and so as toallow said tube to bend in either direction without kinking or closingthe passage through the same. The lower end, f, extends some distancebelow the float, so as to produce a counterbalance, and thereby preservethe upright position of the float. The lower end is closed, while thesides, just a little below the float, are pierced with perforations g g,which admit the liquid at such a distance above the lower end of thenozzle as not to stir up the sediment.

This invention is applicable to many uses for instance, for cisterns,wells, fire-engines,

breweries, tanneries, and, on a smaller scale,

in drug-stores, &c., the object being to draw off from the surface ofthe liquid instead of the bottom, thereby insuring the drawing only ofthe pure liquid, and avoiding the stirring and raising of sediment.

As fast as the liquid is drawn the float falls, and, by this means, thewhole volume of liquid is really raised at a less height than if all isdrawn from the bottom. It is particularly adapted to cisterns and wells,where it can be easily and cheaply applied.

The elevated plaform a is specially adapted to fire-engines, where thefloat may be placed in a river or large body of water, with a quantityof hose thereon and an attendant, the platform serving, in that case, tokeep the float in the upright position under the considerable weight,and obviating accident, while the block 12 serves as the float proper.

Having thus described our invention, we are aware that floats withflexible pipe attached have been connected with pumps. Such we. do notbroadly claim.

What we claim as new is- The combination of the platform a with thefloating block b and nozzle B, for the purpose of supporting theflexible pipe above water, as herein described.

In witness whereof we have hereunto signed our names in the presenceoftwo subscribing witnesses.
